A radioactive substance decays at a rate of 25% every 10 years. Which equation represents the amount of the substance (S) remain

Lelechka [254]

Answer:

$y = 100 * (0.75)^{30$

Step-by-step explanation:

Given

$a =100$ --- Initial Amount

$r= 25\%$ every 10 years

Required

The remaining amount after 300 years

To do this, we make use of:

$y = a(1 - r)^T$

Where

r = decay rate

T = the period of decay

In 300 years, there are 30 periods of 10 years.

i.e.

$T = \frac{300}{10}$

$T = 30$

$y = a(1 - r)^T$

$y = 100 * (1 - 25\%)^{30$

$y = 100 * (1 - 0.25)^{30$

$y = 100 * (0.75)^{30$

Help please. this doesn't make sense

saveliy_v [14]

Answer:

a = 39.2650873379cm

b = 11.5529459767cm

Step-by-step explanation:

a - Use the area of a triangle equation - 1/2 * a * b * Sin(C)

1/2 * 8 * 10 * Sin(79) = 39.2650873379cm

b - Use the cosine rule - c^2 = a^2 + b^2 - (2 * a * b * Sin(C)

64 + 100 - (2 * 8 * 10 * Cos(79)) = 133.4705607398

c = square root of 6.9396506484 = 11.5529459767cm

Put to however many significant figures / decimal places required.
